## How to find the number of days between two dates using Power Automate

One question that is frequently asked on the Power Automate discussion boards is how to find the difference between two dates.  There is not currently a built-in Power Automate expression that will get the job done.  To find out ho to accomplish this requirement, read on...

In my scenario, I will want to find the difference in days between a date stored in a SharePoint list and the current date.

Here's what we are going to do:

1. Convert the two dates to ticks
1. A tick is a small faction on a second
2. Subtract one date from the other
1. The result will be the difference in ticks
3. Convert the ticks to days
1. You're done!

Step 1 - Convert to ticks

Use the ticks() expression to convert both dates to ticks

Step 2 - Get the difference in ticks

Use the sub() expression to find the difference between the two dates in ticks

Step 3 - Convert the difference in ticks to days

There are 864000000000 ticks in a day.  Divide the difference in ticks by 864000000000 to find the difference in days

I suspect that the Power Automate team will eventually give us an expression to find the difference between two dates.  Until then, use the technique outlined above.

I would try looking at the security certificates and trying https it might be the solution

Thanks for this, here's the compacted version I used in Set Variable

``div(sub(ticks(variables('dateSubtractingFrom')),ticks(variables('dateSubtractingWith'))),864000000000)``

Wrap with

``int( )``

if you need the variable in integer format.
